What do I have to do to retrieve a single PDF file for a given publication?

Images are not stored in convenient PDF files which OPS can access and deliver without further processing. OPS could create the illusion of this by converting the images into a single PDF file for you, but this would burden the server to the detriment of other users.

The steps required to fetch the data using the new RESTful OPS are as follows:

Step 1 - Request document availability information:

Step 3 - Assemble the pages:

Several open source tools are available to help you easily assemble the pages as a single PDF file:
